At the time of mauveine's discovery, aniline was expensive. ( hydronium, H3O +--H+ riding piggy-back on a water molecule; water is polar and the + charge of the "naked" proton is greatly attracted to Mickey's chin!) [22] He called it Crystallin. Solutions that contain salts or hydrated metal ions have a pH that is determined by the extent of the hydrolysis of the ions in the solution. In alkaline solution, azobenzene results, whereas arsenic acid produces the violet-coloring matter violaniline.
